LIQUID DISTRIBUTION FOR VAPORIZING. COOLING, AND AERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 662,612, dated November27, 1900. Application filed March 5, 1900. derial No 7,326. (No model.)

To coZZ whom it may concern:

Be it known that 1, WILLIAM HENRY WEIGHTMAN, a citizen of the UnitedStates, residing in the city and State of New York, have inventedcertain new and useful Improvements in Liquid Distribution forVaporizing, Cooling, and Aerating Apparatus, of

i which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to and has for its object an improvement inliquid-distribution, apportionment, and separation in apparatus forvaporizing, cooling, refining, and aerating or like purposes, and moreparticularly an improved mechanism for the careful dis tribution,division, and apportionment of the treated liquid in apparatus of thecharacter described in my application for patent, Serial No. 711,669, ofApril 4, 1899.

The particular aim and object of my invention is to overcome and remedya troublesome difficulty continually met in such apparatus of an unequaldistribution, scattering or sheeting of the liquid under treatment,

and secure a constant overflow-level for the liquid at all portions ofthe fluid-surface independent of all settlement or twist of theapparatus as a whole or of inequalities of the bottom surface of thefluid-distributing chambers or compartments; also, to do away with allhead-pressure of the liquids treated and provide for an equable andclosely-apportioned supply and passage of the liquid to overflow fromthe distributing chamber or compartment to the several distributing waysor channels for overflow and treatment.

My improvements consist, first, in the application of a plurality ofoverflow pipes or ducts to the bottom of the fluid-distributing chamberor compartment and extending the same in an upward direction to apredetermined height and fluid-level, whereby equal quantities of thetreated fluid or liquid are received by the several overflow pipes orducts and transmitted to the several distributing ways or channels belowfor overflow to the vaporizing, cooling, or aerating chamber for desiredtreatment; secondly, in the adaptation and combination of the said mainreceiving and distributing chamber or com partment and its containedupwardly-extending overflow pipes or (luctswith a plurality ofdistributing ways or channels set at two or more levels beneath the saiddistributing chamber or compartment; thirdly, in the special adaptationand combination of a plurality of the main receiving and distributingchambers or compartments each having its plurality of upwardly extendingoverflow pipes or ducts with a plurality of distribut ing ways orchannels located beneath at a single or a plurality of levels, and,fourthly, in means for securing any desired or predeterminedoverflow-levels or for adjusting the height of the individual pipes orducts above the bottom of said main receiving and distributing chamber,so that they shall all receive and deliver equal overflows of the liquidto be treated.

Referring to the drawings, Figure l represents a sectional elevation ofmy improved mechanism for the reception and equable distribution of theliquid in a vaporizing, cooling, refining, and aerating apparatus. Fig.2 represents a sectional view of the same at right angles to the view inFig. 1. Figs. 3 and at represent similar sectional views of my improvedmechanism in which the liquid to be treated is overflowed from a pair oimain receiving and distributing chambers into upwardly-extending pipesor ducts and thence to associate distributing ways or channels. Figs. 5,6, 7, 8, 9, 10, and 11 are detailed representations of methods ofapplying the upwardly-extending overflow pipes or ducts to the bottom ofthe main receiving and distributing chambers 01' compartments.

Similar letters of reference designate like parts, portions, or detailsin all the figures.

Letter Q designates the main receiving and distributing chambers orcompartments of a vaporizing, cooling, aerating, or refining apparatus.receive their supply of liquid to be treated through inlet nozzles orvalves T, the valves T in Fig. 3 receiving their liquid from thesurrounding hollow walls 0 0. (Shown and described in application SerialNo. 711,669, already mentioned.) From the bottom of the chamber orcompartment Q the overflow pipes or ducts P are projected to a fixed orpredetermined fluid-level, as designated at as a: in Figs. 1, 2, 3, and4. The hollow liquid-holding walls 0 may extend to any height Thesechambers or compartments desired above the compartments Q, the valves'I, as shown in Figs. 3 and 4.-, being made use of to control thepassage of the liquid to be treated and its depth within compartments Qto the overflow-level X and the tops of the upwardly-projecting pipes orducts P. The portions Q extend down to and deliver the liquid to betreated to the distributing ways or channels 0, and these overflowingdeliver the liquid to the curtains, gauze, or drops N.

In Figs. 1 and 2 the walls 0 are shown solid, while the inlet of liquidto be treated is through the nozzle T, the admission being controlled byvalve, cook, or any desired means. y

In addition to the use of the ways or channels O as a means for treatingthe fluid inclined outlets S are shown in Figs. 1, 2, 3, and 4, wherebythe liquid is spur-ted against the outer surfaces of the walls of theapparatus to secure a maximum of sheet-like exposure while moving downthe said walls. By the same means S a like spurting against the innerwalls may be effected. In Fig. 5 a detail of this wall-surface spurt isshown, its adjustability to predetermined liquid-level beingaccomplished by the adjusting and jam nuts (1, raising or lowering thepipe or duct to the proper liquid-level for overflow. In case aspecially-strong force of liquid be de sired to pass against thewall-surfaces through these pipes or ducts P S their height above thebottom of the main overflow-compartment may be gaged lower than theoverflows to the ways or channels 0 or lower than the predeterminedwater-level, the delivery being more or less near to the wall-surface.

In Fig. 6 the overflow pipes or ducts are represented as provided with asawtooth edge to prevent any chance intermittent rise, fall, andoverflow of the fluid through capillary attraction.

Figs. 7 and 8 show the overflow pipes or ducts as screwed into thebottom of main compartment Q and secured for adjustment by the jam-nutsa.

In Figs. 9 and 10 the adjustment is secured by means ofthe screw-nozzlesP P, that of Fig. 9 being provided with a bell-mouthp and that of Fig.10 with saw-teeth p at its overflow-top.

Fig. 11 shows an enlarged view in section of screw-nozzle for overflow,with plan view and saw-teeth p. By the higher or lower adjnstment of thesaw-teeth overflow edges a greater or less admission of liquid from thesame level may be obtained.

By the use of the plurality of main receiving and distributing chambersor compartments Q a control of the operation of the plant or apparatusas a whole is gained-as, for instance, by closing the inlet-valves ofeither compartment Q the overflow of liquid in that compartment isstopped and only onehalf of the overflow ways or channels 0 are fed andmade use of, putting the apparatus eeaei on half duty. By the use of theupwardly projecting overflow pipes or ducts P, the same extending to apredetermined liquid-level, all head-pressure is done away with and thefeed to the several distributing ways or channels 0 is the same inquantity and time, no matter how far below or how close to the bottom ofcompartment Q the several distributing ways or channels be located forservice.

While the accompanying drawings show only two rows of the liquiddistributing ways or channels 0 and only two dischargelevels for theoverflow pipes or ducts, any desired number of rows ofliquid-distributing channels or ways may be made use of or any desirednumber of discharge levels or localities for the overflow pipes or duetsmay be adopted to accord with the size, capacity, or method of operationdesired for the apparatus.

What I claim as new, and desire to secure by Letters Patent, is-' 1. Ina liquid -cooling apparatus of the character herein set forth, thecombination of a receiving-compartment for the liquid to be treated, aplurality of distributing-channels, and a plurality of overflowoutlets,each of which is adjustable to a height of overflow-level independent ofany inequalities of level of the bottom of said compartment and extendsdownward to deliver the liquid overflow into associatedistributingchannels.

I 2. In a liquid cooling apparatus of the character herein set forth,the combination of a receiving-compartment for theliquid to be treated,and a plurality of overflow-outlets, each of which is adjustable to aheight of overflow-level independent of any inequalities of level of thebottom of said compartment and extends downward to a close proximitywith the walls of the apparatus, substantially as set forth.

3. In a liquid-cooling apparatus of the character herein set forth, thecombination of a receiving-compartment for the liquid to be treated, aplurality of rows or tiers of distributing -channels, said channelsbeing so staggered that no one channel shall be directly beneath or canreceive the overflow of the channels at higher levels, and a pluralityof overflow-outlets, each of which is adjustable to a height ofoverflow-level independent of any inequalities of level of the bottom ofsaid compartment, and extends downward to deliver the liquid-overflowinto associate distributing-channels substantially as set forth.

4:. In a liquid -cooling apparatus of the character herein set forth,the combination of a plurality of receiving-compartments for the liquidto be treated set at diflerent levels, a plurality of rows or tiers ofdistributingchannels, said channels being so staggered that no onechannel shall be directly beneath or can receive the overflow of thechannels at higher levels, and a plurality of overse m flow-outlets,each of which is adjustable toa height of overflow-level independent ofany inequalities of level of the bottom of said compartments, theoutlets of any one receiving-compartment extending downward to deliverthe liquid-overflow to any single row or tier of the saiddistributing-channels substantially as set forth.

5. In a liquid-cooling apparatus of the character herein set forth, thecombination of the hollow liquid transmitting walls, a plurality ofattached receiving-compartments for the liquid to be treated, saidcompartments being set at different levels, and a plurality ofoverflow-outlets, each of which is adjustable to a height ofoverflow-level independent of any inequalities of level of WILLIAM HENRYWEIGHTMAN.
